I've been using "on commit" along with DNS updating for years:
on commit {
log (
info,
concat (
"Host:", pick-first-value(option fqdn.hostname, option host-name, "(none)"), "=>", pick-first-value(config-option
server.ddns-hostname, "(none)")
," VendorId:", pick-first-value(option vendor-class-identifier, "(none)")
.
.
.
)
);
}
What is it that you want to do?
